    Evaluating a community lifestyle intervention: adherence and the role of perceived support

    Background Interventions that increase participation in physical activity and positive dietary changes may improve the health of the community through modifying the lifestyle contribution to preventable disease. However, previous evaluations have identified concerns about inequitable and unsustainable uptake, adherence and retention within healthy lifestyle schemes.Intervention study The intervention evaluated here was designed to be a 12-week intervention for participants, offering free testing of physiological indicators of health, one-to-one health advice and a range of exercise, activity and cookery classes, at no or reduced cost, at local venues throughout the community. This paper reports the findings from a small qualitative study undertaken to explore the experiences and reflections of those who took part in the intervention to different extents, including those who fully and partially participated as well as those who dropped out or declined to take part.Method Sixteen respondents took part in semi-structured interviews (5 male, 11 female; 8 black, 8 white; age range 25&ndash;85).Findings The findings suggest that participants assessed the healthy lifestyle intervention in terms of how well it met their pre-existing needs and opportunities for change, and that they selected the aspects of the scheme that suited them, interested them and were perceived as delivering salient results. There is also evidence for a stronger role of perceived support in influencing uptake and maintenance of lifestyle changes, and that support was conceptualised by participants as one of the services offered by the scheme. Perceived support and related perceptions of reliance on the scheme to sustain lifestyle changes also suggested that in some cases full adherence to a scheme is not as likely to produce long-term adherence to lifestyle changes as compared to partial, but more realistic adherence and smaller lifestyle changes. Implications for delivering and evaluating healthy lifestyle interventions are also discussed.<br /

    Young peoples’ reflections on what teachers think about family obligations that conflict with school: A focus on the non-normative roles of young caring and language brokering

    In “Western” contexts school attendance is central for an ‘ideal’ childhood. However, many young people engage with home roles that conflict with school expectations. This paper explores perceptions of that process in relation two home activities - language brokering and young caring. We interviewed 46 young people and asked them to reflect on what the teacher would think when a child had to miss school to help a family member. This paper discusses the young people’s overall need to keep their out-of-school lives private from their teachers

    ‘‘Going Where the Questions Are’’: Using Media to Maintain Personalized Contact in Reference Service in Medium-Sized Academic Libraries

    Different approaches to reference service have been added over the years, but the basic premise of the service has not changed–the desire to assist and educate users in locating information. As new technologies are added, such as desktop conferencing and web access, it is important that the personalized contact which is the heart of reference service be preserved. The human touch in the reference process is very important to the success of the reference transaction. Media can be useful in assisting reference librarians in ‘‘Going Where the Questions Are’’ while still maintaining the personal element in creating real-time reference transactions in a technological environment

    Infiltration from the pedon to global grid scales: an overview and outlook for land surface modelling

    Get PDF
    Infiltration in soils is a key process that partitions precipitation at the land surface in surface runoff and water that enters the soil profile. We reviewed the basic principles of water infiltration in soils and we analyzed approaches commonly used in Land Surface Models (LSMs) to quantify infiltration as well as its numerical implementation and sensitivity to model parameters. We reviewed methods to upscale infiltration from the point to the field, hill slope, and grid cell scale of LSMs. Despite the progress that has been made, upscaling of local scale infiltration processes to the grid scale used in LSMs is still far from being treated rigorously. We still lack a consistent theoretical framework to predict effective fluxes and parameters that control infiltration in LSMs. Our analysis shows, that there is a large variety in approaches used to estimate soil hydraulic properties. Novel, highly resolved soil information at higher resolutions than the grid scale of LSMs may help in better quantifying subgrid variability of key infiltration parameters. Currently, only a few land surface models consider the impact of soil structure on soil hydraulic properties. Finally, we identified several processes not yet considered in LSMs that are known to strongly influence infiltration. Especially, the impact of soil structure on infiltration requires further research. In order to tackle the above challenges and integrate current knowledge on soil processes affecting infiltration processes on land surface models, we advocate a stronger exchange and scientific interaction between the soil and the land surface modelling communities

    Historical flash floods in England:new regional chronologies and database

    Get PDF
    There is increasing interest in past occurrences of flooding from intense rainfall, commonly referred to as “flash flooding,” and the associated socioeconomic consequences. Historical information can help us to place recent events in context and to understand the effect of low frequency climate variability on changing flash flood frequencies. Previous studies have focussed on fluvial flooding to reconstruct the temporal and spatial patterns of past events. Here, we provide an online flood chronology for the north and south‐west of England for flash floods, including both surface water and fluvial flooding, with coverage from ~1700 to ~2013 (http://ceg-fepsys.ncl.ac.uk/fc). The primary source of documentary material is local newspaper reports, which often give detailed descriptions of impacts. This provides a new resource to inform communities and first responders of flood risks, especially those from rapid rise in water level whose severity may be greater than those of accompanying peak flow. Examples are provided of historical flash floods that exemplify how the chronologies can help to place recent floods in the context of the preinstrumental record for: (a) more robust estimates of event return period, (b) identification of catchment or settlement susceptibility to flash flood events, and (c) characterisation of events in ungauged catchments
